EDUCATIONAL DEVICE Filed May 10, 1928 2 Sheets-Sheet 2 mis Patented Oct. 22, 1929 FREDERIC B. KNIGHT, OF IOWA CITY, IOWA EDUCATIONAL DEVICE Application filed May 10,

This invention relates to improvements in educational devices, and more especially to such a device adapted for use in learning, correcting, drilling or testing as used in any phase of learning. My invention may also be used in connection with games of the educational variety, or games played purely for amusement.

By the use of my invention questions may be submitted to a pupil on a sheet of paper having the correct answers on the reverse side hidden from view. Space may be provided on the face of the paper, if desired, for the pupil to write his answer to the question. The questions and answers are so arranged on the paper that, by folding the same up progressively from one edge toward the other, the correct answers to the questions may be broughtadjacent said questions seriatim. In using the term question, it is to be understood that I mean to include words, pictures, maps, exercises, problemsy (mathematical and otherwise), puzzles, and the like. By the term answer I mean to include eXplana tions, translations, solutions, comments, criti cisms and the like.

By the use of my invention there is a saving of time and lessening` of eye strain in conL nection with the answering of questions and the correcting of such answers. It is possible for a pupil to write his answer directly on the question sheet in close proximity to the question itself thus eliminating the errors that might occur if the pupil is forced to copy the question on a separate sheet. In correcting the answer, also, there is no time lost in determining which question the answer relates to. The numbering of questions and answers is also eliminated. The correcting of the answers is also very quickly and easily eiected with a high degree of accuracy since by simple manipulation the correct answer is easily brought to a position adjacent the question so that the pupils answer can readily be compared therewith. rIhe ques- 1928.

tion, the pupils answer and the correct answer are all in close proximity and visible at the same time.

Another feature of my invention is the provision of means for giving the pupil a second or third trial or more, to get the correct answer.

It is to be noted also that the correct answers on the printed sheet are upside down on the reverse side thus reducing to a minimum the possibility for the pupil to see the answer through the sheet as he Writes his answers.

Other features and advantages of my inr vention will appear more fully as I proceed with my specification.

In those forms of devices embodying the features of my invention shown in the accompanying drawings, Figure 1 is a view of the face of a question sheet, Fig. 2 is a view ofthe reverse side thereof, and Fig. 3 is a view similar to Fig. 1 showing the paper partly folded. Fig. 4 is a View of the face of a modified form of the question sheet, Fig. 5 is a view of the reverse side thereof and Figs. 6 and 7 are the views similar to Fig. l

showing the sheet folded. Fig. 8 is a View of the face of a modilied form of the question sheet, Fig. 9 is a view of the reverse side thereof and Fig. 10 is a view similar to Fig. 8 showing the sheet folded.

I shall iirst describe the device shown in Figs. l, 2 and 3. As here shown, l0 indicates the( face of a sheet of paper of any shape, here shown as rectangular, and 10a indicates the reverse side thereof. Arranged on the face of the paper, preferably in horizontal lines, are questions or series of questions. As here shown, these questions comprise German words to be translated. For example, I have here shown four `German words on each line, such words being indicated by l1, 11. I preferably number these words, and below each word leave a Space for the pupil to write the answer, such answer in vide on the sheet of paper a line 12 indicating where the paper is to be folded. This line may comprise merely a mark, or it may consist of a crease, row of perforations, or other means assisting the pupil to fold the paper on the line. It is to be noted, that the lines 12, 12 are arranged progressively closer together' from the top toward the bottom of thepaper. This is to permit the paperto be folded on -such linesprogressively upwardly from the bottom toward the top. Or, it might be stated that the paperis frolled up from the bottom by folding the same upwardly progressively on the lines 12,12. It is to be understood, however, that preferably a round roll is not made. After each fold, the paper should lie more or less fiat.

"On the reverse side-of the sheetlthe answers, or,1'inthis case, the translations of the words on the face of the sheetareprmted upside do-wn. In the use of the invention, rthe pupil may write the translationsof the words intheblanl: spaces under such words. For example, as shown in Fig. 3 the :translations of thewords numbered 45, 46, t7` and 48 `are written under 'the same. `After i the translations have been writtenp their correctness-is determined by folding up the lower edge ofthe paper as indicated lby 18,1011 the lowest `fold mark as indicated by 12a. iThis brings the correct translationsftlireetly under the translationswritten bythe pupil as shown in Fi 3, so that comparison can be very easily made. Iiilrewisa in order to test thecorrect- A `ness of the `translations `of -words 415410 .44e

inclusive, thebottomof theI paper is again yfoldedtumardly on thenextcrease mark as indicated; by 12". This will cover 'thewords y L l5 to 48 Ainclusive with their answers .and

bring the correct translations for the words :2l-1 to'lll inclusive directly underneath. In this ,mannen the sheet is folded, or rolled upwardly from vtheloottom so that the correct answers for each row of questionsare .brougzjht adjacent such questions seriatim.

I shall now describe thelform of device showninFigs. 11, `5, 6 and 7. 'This devicelis very similar tothe one shown inFigs. `1,' 2 and 3 except that in theforin here shown, the pupil is given a second trial. 'This is accomplished `by providing y an additional fold mark ,between the question and the space providedfor the pupils answer. 'In the deline is provided a space 113 for the pupils answer. On the reverse side appears the correct answer. In the use of the invention, for example, the pupil may first place an incorrect answer as shown in Fig. 6 where he has stated that X equals 21. In testing the answer the first upward fold is made as shown in Fig. 6 showing that the correct answer is S). The paper may then be given another fold upwardly as shown in Fig. 7 bringing to view the space for the pupils second trial.

,I shall now` describe the formi, ofdeviee shown in Figs. 8, 9 and 10. Asfherefshown,

the face of the paper is indicated by 210 and ythepreverse side .-byy210a. This device resembles in general the device shown in the lotherifigures except that the fold lines are vertical as indicated by 212, instead of horinontal.

As shown inFig. 8, Athevquestions onthe facemay be arranged in two vertical columns at the edges ofthe sheet with two columns between for the pupils responses. v The answers are printedcn the reverse side, asshown. in

Fig. 9. In the use of the Vinvention the sheet is foldedfrom Vthe*right-hand edge in working on 'the questions in the left-hand corner. The first fold, as shown in Fig: 10, brings the answers in view and the second fold provides ,alcolurnn'for second trials. 1In working on the omestions in the right-hand corner/the l tionsonxthe face .thereof anda similar row of answers; on .the reverse side. said questions :in@questions seriatim.
